Talking on your cell phone can be a dangerous affair. Better arm yourself with some kind of defence in case someone tried to tangle with you while you’re gabbing away. What better way than to combine a knuckleduster with a phone case! You may have seen these neat “knuckle” iPhone cases, which is an iPhone case within a knuckleduster. However I wasn’t a fan of the $99 price tag, so I decided to make my own.
I have zero experience with any type of 3D modeling software. So, you can understand my apprehension when I wanted to make my own custom 3D printed object. Luckily there was a very detailed Instructable already written on how to make your own action figure that outlined the process, showing that mashing up existing 3D models is easy. Making my own custom 3D model was so simple I was able to make my model in about an hour on the computer.
This project uses the free modelling tools Netfabb, and MeshMixer. I printed my model through another service, but there’s currently an offer through Instructables to print a model for free! You could make your own for almost nothing! How great is that?!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
